and other conditions, the detectable range may shorten or detection may
not be possible.

mond plates or similar materials are detected on the surface of the parking
space.

WARNING
●Do not rely solely upon the Simple Intelligent Parking Assist System. As
with unequipped vehicles, move forward and back up carefully while
directly confirming the safety of your surroundings and the area to the rear
of the vehicle.
● Do not back up while viewing the multi-information display. Backing up
while only viewing the monitor screen may cause a collision or lead to an
accident, as the image displayed on the monitor screen may differ from
actual conditions. Make sure to visually check the surrounding areas and
the area to the rear of the vehicle with and without the mirror while backing
up.
● Drive slowly while adjusting your speed by depressing the brake pedal
when backing up or moving forward.
● If it seems the vehicle may make contact with a pedestrian, another vehi-
cle or any other obstacles, stop the vehicle by depressing the brake pedal,
and then press the S-IPA switch to turn off the system.
● Use the system in a parking lot with a flat surface.
● Observe the following precautions, as the steering wheel automatically
turns during use.
• There is risk of a necktie, scarf, your arm, etc. being caught on the
steering wheel. Please do not allow your upper body to be close to the
steering wheel. Also, do not allow children close to the steering wheel.
• There is a possibility of injury when the steering wheel turns if you have
long fingernails.
• In case of emergency, stop the vehicle by depressing the brake pedal,
and then press the S-IPA switch to turn off the system.
● Always confirm that there is appropriate space before attempting to park
the vehicle and operate the system.
